Scala AWS Lambda Runtimes
This repo contains a setup to compare the cold startup times of the lambdas written is scala.
| Runtime | Min (ms) | P95 (ms) | Max (ms) | Memory used (MB) | Package size (MB) |
|---|---|---|---|---|---|
| Java8 | 4128 | 4867 | 4953 | 72 | 5.7 |
| Java8 Proguard | 1373 | 1733 | 1957 | 62 | 0.446 |
| Java11 | 4298 | 5181 | 5274 | 96 | 5.7 |
| Java11 JLink | 3061 | 5162 | 6051 | 128 | 23 |
| NodeJS 12 | 125 | 240 | 378 | 65 | 0.0022 |
| Graal Native | 230 | 356 | 413 | 58 | 9.3 |
The raw execution results can be found in the /executions folder.
The data is collected with the CloudWatch Logs Insights using this query:
filter @type = "REPORT"
| fields @timestamp as Timestamp, @initDuration as InitDurationInMS, @duration as DurationInMS, @billedDuration as BilledDurationInMS, @memorySize/1000000 as MemorySetInMB, @maxMemoryUsed/1000000 as MemoryUsedInMB
| sort Timestamp desc
| head 200
